Spotlight can be configured to raise an alarm on custom counters. For more information, see Add alarms to custom counters and SQL Server | SQL Activity drilldown. To configure how often Spotlight collects Custom Counter data, see Configure | Scheduling.
Configure custom counters from the Spotlight Client
Click Configure | Custom Counters.
Select template or connection to configure
Select the SQL Server or Windows connection from the list of available options. Spotlight will show the configuration for that connection. Make changes if required. Optionally use the options at the bottom of the screen to apply the same configuration to other SQL Server (Windows) connections or save the configuration as a template.
Alternatively, select a template to configure. The templates you have previously saved for Spotlight Custom Counter configuration are listed. On selecting the template you can view / modify / reapply the template configuration. You can delete or rename the template. For more information, see Configuration templates.

Custom Counter properties
The name of the custom counter. The name is displayed in the Custom Counters drilldown.
For SQL Server queries, use T-SQL syntax. For Windows queries, use WMI. It is recommended that the query return only one column and one row. For all custom counter queries, Spotlight reads only the first column of the first row of data. Any additional data is ignored. To return multiple values, use more than one query. See the following for examples of custom counter queries.
Pages Allocated (SQL Server)
select cntr_value from sys.dm_os_performance_counters where object_name like '%:Access Methods%' and counter_name = 'Pages Allocated/sec'
Open Files (Windows)
SELECT FilesOpen FROM Win32_PerfRawData_PerfNet_Server
